1. Use Chase Ultimate Rewards Credit Cards

Your best option for earning United miles is actually to earn Chase Ultimate Rewards points. The Ultimate Rewards credit cards often come with several bonus categories that can help boost your earning potential.

Sign-up bonuses for these cards often vary between 15,000-80,000 points with the premium cards having the higher bonuses. To earn the sign-up bonus, you must meet a minimum spend requirement. Once you do so, points generally post to your account when your statement closes but it can take up to 8 weeks.

Keep in mind that you must have at least 1 of the premium Ultimate Rewards cards (i.e. one with an annual fee) to be able to transfer all your points to your United account.

Recommended Chase Cards (Personal)

Chase Sapphire Preferred® Card - This is our favorite beginners travel rewards card which has a 60,000 point bonus (highest ever) after you spend $4,000 on purchases in the first 3 months from account opening.

This sign up bonus is worth $750 in travel purchases (flights, hotels, car rentals etc) when you redeem your points through Chase's travel portal, which works like Expedia. The bonus alone could get you multiple round-trip flights or hotel stays.
Chase Sapphire Reserve® - Consider this premium card if you want to get into a lot of airport lounges. The current sign up bonus is 50,000 points after you spend $4,000 on purchases in the first 3 months from account opening. You'll also get a $300 travel credit per year which wipes away a big chunk of the $450 annual fee.
Chase Freedom Unlimited® - A simple, no annual fee card that earns you 3% cash-back on all purchases in your first year (up to $20,000 spent), then 1.5% on all purchases after that. Just know that you won't get any travel benefits or the ability to earn bonus points with this card.

Recommended Chase Cards (Business)

Ink Business Preferred℠ Credit Card - This is our #1 recommended business card and comes with a whopping 80,000 sign up bonus after you spend $5,000 on purchases in the first 3 months after account opening. This bonus is worth $1,000 when you redeem through Chase Ultimate Rewards for travel purchases (flights, hotels etc). Also, if you pay for your cell phone bill with this card, you can get up to $600 in cell phone insurance coverage per year.
Ink Business Cash℠ Credit Card - earn $500 bonus cash back after you spend $3,000 on purchases in the first 3 months after account opening. In addition, get up to 5% cash back on a range of business expenses. A simple, $0 annual fee card.

2. Use Chase United Credit Cards

Your other option is to use United MileagePlus co-branded cards, which are listed in the table below.

Depending on the card, you may qualify for a sign-up bonus of 30,000-50,000 points after you reach the minimum spend threshold within the first 3 months. Periodically, Chase offers sign-up bonuses worth an extra 20,000 points, for 50,000-70,000 points total!

If you’re lucky enough to apply for a card during such a promotion, you can be halfway (or further) to your goal of 100k points within a few months. Sign up for a personal and business card, and you can meet (or beat) your goal as soon as you spend the required amount!

It can take up to 6-8 weeks for bonus points or a statement credit to appear after you qualify, but points usually post to your MileagePlus account much sooner than that.
